直流电机转速检测与脉宽调速电路设计的探讨

Discussion on the design of DC motor speed detection and pulse-width modulation circuit model

为了深化学生的理论基础学习,进一步提高工程实践能力,指导学生设计和制作直流电机的转速检测与脉宽调速电路模型。主要让学生设计转速检测与脉宽调速电路。这两个电路的设计既可以独自成为一个设计实验,也可作为组合性实验,同时对电动自行车的调速具有借鉴意义。

In order to deepen the theoretical basis of students and improve their ability of the engineering training ability, the paper supplies a guide for students to design and produce DC motor speed detection and pulse-width modulation circuit model. Speed detection and pulse-width modulation circuit are the main designs for students, which can be designed either as the single design experiments respectively or as the whole experiment together. As the combined experiment, it offers a reference for the electric bicycle speed modulation.
